Abstract

A beam locating device for varying the effective point of origin of an electronic beam of a cathode ray tube that is deflected from a predetermined center of deflection through the reflection screen of said tube, characterized in that said device comprises a support member that at least partially surrounds the axis of symmetry of the aforesaid tube in an intermediate position of said deflection center and said display; and magnetic means on said support member to develop an auxiliary deviation of the frame of predetermined configuration, in said tube between said deflection center and said screen, with the integral of the curve of the intensity component of the field transverse to the beam trajectory in periods of a predetermined direction of its beam distance as a function of the said distance from the center of deflection that is substantially the same along all trajectories of the beam.
